microphone feature with Windows 10

[coulonnus]

When I record myself with my electronic organ the volume of each note drastically decreases after a fraction of second, making the recording awfull. Same with the camera or Pamus MP3 recorder. Same with the build in microphone or another one I plug.

Can I get rid of this misfeature? Perhaps this is supposed to improve speech recordings.

Same with piano, electronic organ and pipe organ. Good when I hum or whistle a tune. Intermediate - but atroucious! - when I play viola.

Finally the solution was to open Sound, Manage audio devices, Recording, Microphone, Advanced and unckeck Enable audio enhancements. Hope this will be useful.
